Problems solved by technology

[0004] 1. When the solvent-based surface treatment agent is used to treat synthetic leather products, the organic solvent contained in it will cause the bottom layer of synthetic leather or artificial leather to dissolve, and the treated synthetic leather will not feel good;
[0005] 2. The organic solvent in the solvent-based surface treatment agent is not only expensive, smelly, easy to pollute the environment, but also has safety hazards such as flammability and explosion;
[0006] 3. The comprehensive effects of synthetic leather products obtained after the surface treatment agent is treated with synthetic leather, such as visual effect, viscosity, stability, hand feeling, etc., are not good

Abstract

The invention discloses an aqueous PU fog face rubbing surface treatment agent for synthetic leather, comprising the following components by weight percentage: 40-50% of aqueous polyurethane resin, 30-40% of water, 3-6% of matting agent, 1-5% of organic silicon antifoaming agent, 0.5-5% of organic silicon flatting agent and 0.5-5% of aqueous polyurethane thickener. The surface treatment agent provided by the invention takes water as solvent which replaces poisonous solvents such as dimethylformamide and butanone and has the performances of non-combustion, safety, environmental protection and less cost; after being treated by the surface treatment agent provided by the invention in a wiping manner, the prepared leather has good fog face rubbing effect, sharp contrast between colours of a surface layer and a rubbing layer, good visual effect and excellent general effect.

Description

technical field [0001] The invention relates to a chemical composition, in particular to a water-based PU matte surface treatment agent for synthetic leather and a preparation method thereof. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future, and synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. Synthetic leather is usually a sheet-like product made of a polyurethane resin composition laminated on a substrate such as non-woven fabric, woven fabric or woven fabric. Its structure includes a base fabric and a polyurethane resin layer attached to the base fabric. Polyurethane The resin surface layer mainly plays the role of decoration and imitation leather visual effect. [0003] According to the needs of aesthetics, after the production of synthetic leather, the surface treatment agent is usually used for surface treatment to achieve visual effects s...
